发送大量电子邮件 [英] Sending solicited mass email

问题描述

我们公司进行工作环境调查，这些调查在线填写。所有参与者都通过电子邮件（包括个人代码）向他们的调查发送了一个链接。

我们的一些客户有数以百计的员工，有时甚至数以千计。 / p>

我们目前的解决方案只是使用我们的SMTP服务器发送，没有任何形式的限制（VB6，CDO）。 （所有收件人通常在同一个域内[e-mail]）
这不是一个很好的解决方案，您可以想像，这会触发客户端环境中的每个反垃圾邮件/防火墙/网守事件。我们预先与他们的IT部门联系，让他们将发送服务器和发件人邮箱地址列入白名单。

我们最常遇到的问题是：

1. 接收服务器只收到20-50封邮件，拒绝其他（反垃圾邮件措施）。我们有时可以通过让它将公司列入白名单。有时候，这样做不起作用。


2. 禁用弹出不正确的邮件地址越来越正常。这给我们没有指示邮件是否已经交付。不管相信与否，大多数客户都从他们的人力资源系统而不是他们的邮件系统给我们他们的电子邮件列表。

有没有人有建议更好的方法来做到这一点？我们不能成为发送合法大众电子邮件的唯一公司吗？ ：）

解决方案

有一个关于编码恐怖的好文章详细介绍了发送电子邮件的过程。简而言之：

1. 通过添加 DomainKey 。


2. 添加发件人ID SPF记录到您的DNS设置。

您还可以使用外部邮件发送服务，如 Campaign Monitor ，它将为您检查这些设置。

Our company does work environment surveys, and these surveys are filled in online. All participants are sent a link to their survey in an email (personal code included).

Some of our clients have employee counts in the hundreds and sometimes in the thousands.

Our current solution is just using our SMTP-server to send this, without any form of throttling (VB6, CDO). (All recipients are usually "inside" the same domain, [e-mail]) This is not a good solution, as you may imagine, this triggers every anti-spam/firewall/gatekeeper event in the clients environment. We are put in contact with their IT-department beforehand and get them to whitelist our sending server and sender-mail address.

The most usual problems we run in to are:

1. Receiving server only grabs the 20-50 first mails and rejects the rest (anti-spam measure). We sometimes can get by this by getting the it-company to whitelist us. Sometimes however, this does not work.
2. It's getting more and more normal to disable bouncing of incorrect mail addresses. This gives us no indication of whether a mail has been delivered or not. And believe it or not, most clients gives us their email list from their HR-system, not their mailsystem.

Does anyone have any suggestions for a better way to do this? We can't be the only company sending legitimate mass emails? :)

解决方案

There is a good article on Coding Horror that details the process of sending e-mail. In short:

1. Verify your domain records by adding a DomainKey.
2. Add an Sender ID SPF record to your DNS settings.

You could also use an external mail sending service like Campaign Monitor, which checks these settings for you.
